IIRC, multiple codeowners means multiple approvals. do we want this?

TBH, i want to keep myself in loop for future changes to this repo. Hence added my current team, also I can pull you in when a complicated code requires review as you are not in any of the current owner teams😉

I am also fine removing the @elastic/obs-ux-infra_services-team
